Someone who likes fondling a guys balls until it causes testicallingitus (you're sack inflates until it eventually asplodes)
Man:Last night was insane! I hooked up with this prostitute with this really sexy low voice and she was a total nug fuggler!
Friend:It's probably wasn't worth the loss of your sack though, right?
Man:Meh it isn't all that bad, atleast I feel more feminine now.
